From 205cb37b89ab37db553907e5ac17962eec561804 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 14 Oct 2009 23:22:17 +0200 Subject: kill-the-bkl/reiserfs: definitely drop the bkl from reiserfs_ioctl() The reiserfs ioctl path doesn't need the big kernel lock anymore , now that the filesystem synchronizes through its own lock. We can then turn reiserfs_ioctl() into an unlocked_ioctl callback.
